Semantic程序代碼解析、分析和比較工具

semantic 是一個(gè) Haskell 庫和命令行工具，用來解析、分析和比較程序代碼。

使用方法：

Parse

Usage: semantic parse ([--sexpression] | [--json] | [--json-graph] | [--symbols]
                      | [--dot] | [--show] | [--quiet]) [FILES...]
  Generate parse trees for path(s)

Available options:
  --sexpression            Output s-expression parse trees (default)
  --json                   Output JSON parse trees
  --json-graph             Output JSON adjacency list
  --symbols                Output JSON symbol list
  --dot                    Output DOT graph parse trees
  --show                   Output using the Show instance (debug only, format
                           subject to change without notice)
  --quiet                  Don't produce output, but show timing stats

Diff

Usage: semantic diff ([--sexpression] | [--json] | [--json-graph] | [--toc] |
                     [--dot] | [--show]) [FILE_A] [FILE_B]
  Compute changes between paths

Available options:
  --sexpression            Output s-expression diff tree (default)
  --json                   Output JSON diff trees
  --json-graph             Output JSON diff trees
  --toc                    Output JSON table of contents diff summary
  --dot                    Output the diff as a DOT graph
  --show                   Output using the Show instance (debug only, format
                           subject to change without notice)

Graph

Usage: semantic graph ([--imports] | [--calls]) [--packages] ([--dot] | [--json]
                      | [--show]) ([--root DIR] [--exclude-dir DIR]
                      DIR:LANGUAGE | FILE | --language ARG (FILES... | --stdin))
  Compute a graph for a directory or from a top-level entry point module

Available options:
  --imports                Compute an import graph (default)
  --calls                  Compute a call graph
  --packages               Include a vertex for the package, with edges from it
                           to each module
  --dot                    Output in DOT graph format (default)
  --json                   Output JSON graph
  --show                   Output using the Show instance (debug only, format
                           subject to change without notice)
  --root DIR               Root directory of project. Optional, defaults to
                           entry file/directory.
  --exclude-dir DIR        Exclude a directory (e.g. vendor)
  --language ARG           The language for the analysis.
  --stdin                  Read a list of newline-separated paths to analyze
                           from stdin.
